Deployed Link- https://task-management-system-afof.onrender.com/

Overview

The Task Management System is a backend API built using Node.js and Express.js. It provides task management functionality with secure user authentication and role-based access control. The API uses MongoDB to store data and follows best practices for code quality, including dependency injection and proper design patterns.

Features

• User Registration with JWT-based Authentication
• Role-Based Access Control (Admin, User)
• CRUD Operations for Tasks
• Filtering Tasks by Priority, Status, and Assigned User
• Secure Endpoints with Route Guards and Input Validation
• Dependency Injection for Authentication, Role Management, and Task Handling

Technologies Used

• Node.js
• Express.js
• MongoDB (Mongoose)
• JWT (JSON Web Token) for Authentication
• bcryptjs for Password Hashing
• dotenv for Environment Variables
• Postman for API Testing
